配置IPv6邻居发现示例
本举例介绍IPv6邻居发现的配置过程。
操作步骤
- 配置接口的链路本地单播地址，在接口下执行ipv6 enable命令后，系统会自动为该接口生成一个链路本地地址。
<HUAWEI> system-view[~HUAWEI] sysname DeviceA
[*HUAWEI] commit
[~DeviceA] interface gigabitethernet 0/1/0 [~DeviceA-GigabitEthernet0/1/0] undo shutdown [*DeviceA-GigabitEthernet0/1/0] ipv6 enable [*DeviceA-GigabitEthernet0/1/0] commit
- 配置接口的EUI-64单播地址和RA消息中的前缀
在DeviceA上配置需要发布的RA前缀消息并打开RA消息的发布开关后，PC才能自动获得路由器RA报文的地址前缀消息。
[~DeviceA-GigabitEthernet0/1/0] ipv6 address 2001：db8::/32 eui-64 [*DeviceA-GigabitEthernet0/1/0] ipv6 nd ra prefix 2001：db8::/32 1000 1000 [*DeviceA-GigabitEthernet0/1/0] undo ipv6 nd ra halt [*DeviceA-GigabitEthernet0/1/0] commit [~DeviceA-GigabitEthernet0/1/0] quit
- 验证配置结果
如果配置成功，可以查看配置的链路本地单播地址和EUI-64全球单播地址，以及接口状态为Up，IPv6协议状态为Up。
